Transporting station and method for transporting fish in a transporting direction, which is transverse to their longitudinal extent, and fish-processing machine having such a transporting station

Abstract

The invention relates to a transporting station (10), designed and configured for transporting fish transverse to their longitudinal extent in a transport direction T, comprising a conveying device (11) for transporting individual, separated fish in a lying position along a transport path TL from an entry region E of the conveying device (11) to an exit region A of the conveying device (11), wherein the conveying device (11) comprises a rotationally driven transport element (12) which is characterised in that the conveying device (11) is assigned a change-over device (13) which is designed and configured and is in operative connection with the conveying device (11), in such a manner that the fish can be transferred automatically from the lying position on the transport path TL of the conveying device (11) into a suspended position on a transport path TH of the change-over device (13). The invention is also concerned with a fish processing machine (47) having such a transporting station (10), and with a corresponding method.

AI Technical Summary

Benefits of technology

The invention is a transporting station that automatically transfers fish from a conveyor belt to a suspended position for processing. This ensures precise and symmetrical positioning of each fish, and high yield-efficiency processing can be performed. The transfer is achieved using a change-over device that connects to the conveying device, allowing for unobstructed transfer without colliding with the swinging fish. The conveyor belt speed is synchronized with the fish's movement to prevent collisions. The invention combines the advantages of existing transporting stations, such as ease of handling and simple structure, with the benefits of coordinated speed adjustments and prevention of fish collisions.

Problems solved by technology

Due to the “skew position” of the fish, the knife pair cannot separate the head from the body without yield loss.

Processing of fish lying on their sides, in particular heading of the fish, is also a disadvantage for another reason.

The uneven weight distribution in relation to the axis of symmetry between the two halves of the body of the fish can lead to an inadequate cutting result due to the undefined position of the fish.

Orientation of the horizontal fish into a defined position in relation to the axis of symmetry cannot be achieved or can only be achieved with considerable technical effort due to product-dependent and / or quality-dependent and / or physical factors.

Manual loading of such transporting stations with fish on the one hand, and manual orientation of the fish for the heading cut on the other hand, lead to undefined orientation of the fish on the one hand and to high physical stress of the operators on the other hand.

In addition, the automation of such work steps on the one hand, and fixing of the fish in the suspended position on the other hand, requires a considerable effort in terms of design.

Such transporting stations therefore have various disadvantages which is why transporting stations with suspended transport of the fish, head upwards, have not prevailed over transport in a lying position despite the improved symmetrical position of the fish which is improved by comparison.

All the solutions known from prior art have problems concerning symmetrical orientation of the fish with the result that yield losses occur during processing of the fish.
